CHURN.

SPECIFICATION forming part of Letters Patent No. 439,067, dated October 21, 1890.

Application filed May 16, 1890. Serial No. 352,110. (No model.) A

To all whom it may concern..- y

Be it known that I, WILLIAM J. HERsoM, a citizen of the United States, residing at Stockton, in the county of San Joaquin and State of California, have invented certain new and useful Improvements in Churns; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it ap- 1o pertains to make and use the same, reference being had to the accompanying drawing, and to the letters of reference marked thereon, which form a part of this specification.

The figure is a side elevation of my im- 1 5 proved churn, a part of the vessel being broken out to display the dasher.

My invention relates to an improvement in churns; and it consists in the construction, combination, and adaptation of parts, as will 2o be hereinafter more fully set forth, and particularly pointed out in the claim appended.

The letter A represents the vessel which receives the cream.

B is the lid, having on the rim two lugs B opposite to each other, carrying set-screws B2,

which secure the feet of a yoke-frame C, having an arm C', which, and the top of-the yoke C, forms the center and top bearings for a vertical shaft G, which has a pinion F2 loose 3o upon it and resting on the bearing C', be-

neath which is a neck F3 of the pinion F2, attached rigidly to the pinion F2 and loose upon the shaft G', and provided With pins which enter the face of a collar H, likewise 3 5 loose upon the shaft G.

The pinion F2 meshes with a bevel-gear F, which meshes with a bevel-pinion F', which is loose upon the shaft G, and is provided with a neck, which is attached to a collar G2, 4o loose on the shaft G', which collar is rigidly attached to the face of a balancewvheel G, having a socket fitting upon the square head G3 of the shaft G The shaft G has its bottom bearing in a step I2 at the bottom of the vessel A, and has a collar I loose upon it just above the step I2. Dasher-wings I are rigidly attached at their feet to the collar I and at their heads to the collar H. These wings and the shaft G within the vessel are provided with suit- 5o able blades J, those on the shaft G being at opposite sides.

The large bevel gear-wheel F has attached to it a horizontal turning-shaft E, having its bearings in a two-part tube C2, attached to 5 5 the sides of the yoke C, and having a handle D at its outer end. By turning the handle D motion is imparted to the gear F, which in turn sets the pinions F and F2 in motion, the pinion Fl setting in motion the shaft G 6o and the pinion F2 setting in motion the collar H and its Wingsland foot-collar I', thus causing the four sets oi blades J -in sets. of twoto rotate oppositely to each other, insuring a most thorough agitation of the cream within the vessel.

In order to remove the dasher apparatus, shaft, and yoke from the vessel, the set-screws B2 are withdrawn, permitting all the above to be removed, or the shaft G and the yoke 7o C and attached gearing may be removed from the wings I and the collars II and I.

The {1y-wheel G from its peculiar position gives great aid and force in turning the dasher when the cream becomes Stift. 7 5

I am aware that the various parts of my device are old when separately considered, and that many of them have been used in combination, and therefore claim only the parts in the exact construction and particular 8o arrangement hereinafter specifically pointed out.

Having thus described my invention, what I claim is The herein-described churn, consisting of the vessel A, the lid B, with the lugs B and their set-screws B2, the yoke C, its arm C', the shaft G', having its upper bearings` on such yoke C and foot C and its lower bearings on step I2 at the bottom of the vessel A, 9o the pinion F2, loose on the shaft G and having a neck F2, provided with pins entering a collar H, the gear-Wheel F, meshing With the pinion F2 and with a pinion F upon the shaft G such pinion being provided with a wheel F, all arranged substantially as shown neck fast to a collar G2, which is' fast to a and described. ro balance-Wheel G, having a socket settin g upon In testimony whereof I affix my signature in a square head G3 of the shaft G', the Wings presence of two Witnesses.
